Real Madrid forward Gonzalo Higuain has admitted that winning against Borussia Dortmund in the Champions League will not be easy.
The Spanish champions will confront the German club over two legs in the semi-finals of Europe's premier club competition.
"Borussia Dortmund are a tough opponent, they have won the last two league titles in Germany," he told reporters.
"They are an opponent that we have to respect but we are Real Madrid and we have to go out to win the tie."
Madrid failed to beat Dortmund in two games in the group stage of the Champions League earlier this season.
